With this issue we initiate the policy of expanding the scope of Tulane Studies in Philosophy to include, in addition to the work of members of the department, contributions from philosophers who have earned advanced degrees from Tulane and who are now teaching in other colleges and universities. The Editor THE LOGIC OF OUR LANGUAGE ROBERT L. ARRINGTON Wittgenstein wrote in the Tractatus that "logic is not a body of doctrine, but a mirror-image of the world. " 1 In line (...) with his suggestion that a proposition is a 'picture', Wittgenstein argued that propositions 'show' the logical structure of the real. He was insistent, however, that "the apparent logical form of a proposition need not be its real one. " 2 As a result of this we can misunderstand the structure of fact. Philosophical problems arise just when "the logic of our language is mis understood. " 3 It is common knowledge that much of this view of logic was rejected by Wittgenstein himself in the Philosophical Investi gations. There we are told that language has no ideal or sublime 4 logic which mirrors the structure of the extra-linguistic world. Consequently, inferences from the structure of language to the structure of that extra-linguistic world are invalid. Reality can be 'cut up' in any of a number of ways by language. Wittgenstein adopted a view of philosophy which would render that discipline a non-explanatory, non-critical study of the multiple ways in which language can be used. (shrink)

What has traditionally been labelled ‘Aristotle's theory of causes’ would be more intelligible if construed as ‘Aristotle's theory of explanations’, where the term ‘explanation’ has substantially the sense of Hempel and Oppenheim, who construe explanations as deductions. For Aristotle, specifying ‘causes’ is constructing demonstrations.

Writing from a scientifically and philosophically informed perspective, the authors provide a critical overview of the conceptual difficulties encountered in many current neuroscientific and psychological theories.

The book "Philosophical Foundations of Neuroscience" is an engaging criticism of cognitive neuroscience from the perspective of a Wittgensteinian philosophy of ordinary language. The authors' main claim is that assertions like "the brain sees" and "the left hemisphere thinks" are integral to cognitive neuroscience but that they are meaningless because they commit the mereological fallacy—ascribing to parts of humans, properties that make sense to predicate only of whole humans. The authors claim that this fallacy is at the heart of Cartesian (...) dualism, implying that current cognitive neuroscientists are Cartesian dualists. Against this claim, we argue that the fallacy cannot be committed within Cartesian dualism either, for this doctrine does not allow for an intelligible way of asserting that a soul is part of a human being. Also, the authors' Aristotelian essentialistic outlook is at odds with their Wittgensteinian stance, and we were unconvinced by their case against explanatory reductionism. Finally, although their Wittgensteinian stance is congenial with radical behaviorism, their separation between philosophy and science seems less so because it is based on a view of philosophy as a priori. The authors' emphasis on the a priori, however, does not necessarily commit them to rationalism if it is restricted to conceptual or analytical truths. (shrink)

Behaviorism is belief that psychological states and traits are behavioral dispositions. This is normally interpreted by critics to mean that every person in state S is disposed to behave in way B. So interpreted, behaviorism is subject to the objection that there are spartans who feel pain but do not moan and groan. However, with few exceptions, behaviorists have not contended that everybody who is in a given state of mind necessarily behaves in the same obvious way. Instead, behaviorists have (...) typically contended only that being in one state of mind rather than another makes a discoverable difference to how one is disposed to behave. Thus, behaviorism does not require that spartans moan and groan when in pain. All it requires is that they behave differently when in pain than when not in pain. (shrink)

"Intentional behaviorism" is Gordon Foxall's name for his proposal to mix the oil of mentalist language with the water of empiricist behaviorism. The trouble is, oil and water don't mix. To remain scientific, the language of behavioral science must remain non-mental. Folk psychological ascriptions of belief and desire do not explain the patterns of behavior identified by behavior analysis; they merely describe these patterns in less scientific language. The underpinnings of these patterns, if not intentionality, must be sought in physiology, (...) particularly neurophysiology. Intentionality is an aspect of language, not the world. If we find it in the world, it is because we have put it there. (shrink)

Philosophical critics standardly read behaviorism as a program for defining the concepts of folk psychology in equivalent behavioral terms. This is a misreading. Behaviorism is a program for getting rid of ill-defined mentalistic terms in favor of better defined behavioral idiom. In short, it is a program not for conceptual analysis but for verbal reform. Therefore, criticizing behaviorists for failing to define mentalistic concepts is like criticizing opponents of the Spanish Inquisition for failing to define witchcraft.

City College of New York The hereditarian theory of race differences in IQ was briefly revived with the appearance of The Bell Curve but then quickly dismissed. The authors attempt a defense of it here, with an eye to conceptual and logical issues of special interests to philosophers, such as alleged infirmities in the heritability concept. At the same time, some relevant post-Bell Curve empirical data are introduced.

Nor does the converse relation hold. Freedom does not insure facility, as the following case shows. Jones is free, any time he wishes, to press five hundred pounds. There is no law against it and nobody will object if he makes the attempt. Nevertheless, Jones, who weighs only a hundred pounds himself, is unable to lift fifty pounds, much less five hundred, and must fail if he tries. Again, the distinction is that between "may" and "can." Jones may lift five (...) hundred pounds; he can't. He has the prerogative but not the power; he has the right but not the strength. (shrink)

In an earlier essay in this journal, the estimable John Staddon charges B. F. Skinner and E. O. Wilson with committing several fallacies while promoting evolutionary ethics. The present essay replies that what Staddon regards as fallacies are signal contributions to a naturalistic understanding of ethical choice and language.

What are "private events" and what is their significance? The term is B. F. Skinner's, but the idea is much older. Before J. B. Watson challenged their methods and their metaphysics, virtually all psychologists assumed that the only way to discover a person's supposedly private states of mind was to ask her about them. Not a believer in minds, Skinner nevertheless agreed that sensations, feelings, and certain unspecified forms of "covert behavior" cannot be observed by others, because they take place (...) inside the body underneath the skin. Then he added that these inner events are of interest only to the physiologist; the concern of the behavior analyst is how intact organisms interact with their environment, not how their inward parts interact with each other. That compromise enabled Skinner to pursue behavior analysis in disregard of neurophysiology, which there was at the time no good way to study anyhow. But Skinner's talk of ineluctably private events was ill considered and ill conceived. There is no well understood sense in which people observe their own sensations, feelings, and "covert behavior," but if these take place inside the body, as it is reasonable to believe, the physiologist can observe them given the sophisticated new machines now available. And since these events inside the body vary with circumstances and influence behavior, the psychologist cannot afford to ignore what the physiologist has to say about them. Black box psychology is out of date. Though it is opaque, the skin is not an epistemological barrier. (shrink)
